A QUALITY HOME
STRENGTH PLUS ECONOMY
MAKE IT PRACTICAL!
A home is a castle, but not a castle in the
air. A home is lumber — 2x4 studs, 1x8
boards, 2x10 joists. Today this lumber is
graded for specific uses. Each grade —
No. 1, No. 2 and No. 3, for example, in
Douglas fir and West Coast hemlock fram-
ing lumber — is designed to meet certain
requirements. In any well -constructed
house there are places where No. 1 be-
longs. But there are many places also
where the wise builder with an eye for
savings finds that No. 2 and No. 3 amply
meet the need.

JOISTS and RAFTERS
JOISTS AND RAFTERS
No. 3 Dimension: A utility grade valuable for studding
in walls and partitions, solid bridging and filler pieces.
No. 2 Dimension (HOOf): A stress grade used extensively
for joists, rafters and planks. Where extra stiffness is re-
quired it may be used in a larger size as an alternate for a
higher grade of a smaller size. (Stiffness is determined by
size rather than by grade.)
No. 1 Dimension (1450ft: A stress grade of higher rating.
For joists, rafters, plank and similar horizontal load bear-
ing members. Mueh used in truss framing.
Select Structural (1900f Douglas fir, 1600f West Coast
hemlock): A high grade combining exceptional strength
and appearance. Mostly used in engineered structures and
for architectural effect in exposed trusses, beams, joists,
rafters and for heavy roof sheathing where appearanee is of
(NOTE: No. 2 Doujrlas fir and West Coast hemlock joists and rafters can be used conservatively on spans not exceed-
ing three-fourths the maximum allowable span for No. 1 joists and rafters of the same thickness and depth.)
DEPENDABILITY PLUS ECONOMY
JUST LIKE FINDING IT!
Using the proper grades of lumber
ins lower eosts — money saved.
Douglas fir and West Coast hemlock
dimension lumber provides absolute de-
pendability for specified uses. With that
dependability assured, the thrifty home-
builder can "find" money for other pur-
poses by selecting the proper grades.
Because of the knots, short strips of bark, white srakfl
pitch pockets or other characteristics which distinguish
the grade. No. 3 is not as pretty us No. L/1*ut the
"prettiness" of surfaces which are not exposed is of no
importance. Of eery great important is Ou requirement
that a hotm ht "built to last." It inusr be sound. The
builder must know it is sound. Xo/3 Douglas fir and
West Coast hemlock lumber, used/Where it belongs, can
give him that assurance — at a/saving!
For one-story walls, 2x4 studs of No. 3 Douglas fir and
W est ('oast hemlock are widely used because of their
stiffness, ruggedness, permanence and economy. In
two-story Western frame construction. No. 2 studs are
used for the ground floor and No. 3 Studfl for the uppc
floor. In each case engineering experience has deter-
mined that the grade will provide the required strength
with a reliable margin of safety to spare.
In addition to studs, sub-floors, sheathing and m<
boards, other established uses for No. 3 Douglas fir an
West Coast hemlock include:

COMFORT PLUS ECONOMY
Comfort counts in home -building, and
proper insulation means comfort. An inch
of wood has insulating qualities equal to
4 l h inches of ordinary bricks, 7 inches of
concrete, or J2 f /2 inches of stone. That's
why wood sheathing has been preferred
The primary requirements for roof boards and sheathing .
are ease of working, ease of nailing, and moderate
shrinkage. Douglas fir and West Coast hemlock boards
are supreme in meeting these requirements. No. 3 can
be counted on to give sound, lasting value — at a figure
your pocketbook will like.
For your own protection make sure that the following
is included in your written specifications:
"All grades shall conform to the grades as published in
the official grading and dressing rules of the West Coast
Bureau of Lumber Grades and Inspection."
You know your home will be beautiful. Make sure it is
soundly — and economically — built by using the right
grades of lumber in the right place.
There are economies, too, in the selection of the following types of siding:

Hemlock: Highest quality wood siding, entirely vertical grain
and practically free from all defects. The wide widths permit
broad exposure, and the unusually thick edges produce pleas-
ing shadow lines.
"A" Cedar, "B" Spruce and "C" Hemlock: For high qual-
ity construction, usable without waste. Permits mixed vertical
and flat grain, but contains no defects that will not cover with
"B" Cedar: A slightly lower grade than "A" Cedar. By cut-
ting out a few defects a paint grade for medium quality con-
struction is obtained.
"C" Cedar, "C" Spruce and "D" Hemlock: Is adaptable to
use by cutting out more serious defects. An economical grade
for medium or low cost construction.
